For the first time, I have two paths to the same hosts. VSE/ESA 2.7 which has a connection to a vswitch to an OSA device on the 390 LPAR that connects to a OSA device on the IFL LPAR that connects to a vswitch to zLinux (SUSE 9).
The second connection is VSE/ESA 2.7 which has a connection to a hipersocket on the 390 side that connects back on the IFL side to the same zLinux image. To test the connection, I FTP'ed a large file from VSE to Linux. On the Linux side, I did the ifconfig command which shows the number of bytes received and transmitted on each off the defined paths. To my supprise, Linux was receiving data from VSE over the hipersocket, but transmitting the replies over the OSA connection. OK, basic routing mistake. I only had a default route setup in the Linux image. But my quesiton is, is there a better utility then ifconfig to show packet routing? Something that comes with zLinux? NETSTAT DEV shows the same info on the VM side, but now that vswitch handles all the routing, NETSTAT only shows information for those applications that use the VM IP stack. In this case, the system was idle and I could see what paths were being used. But on a more active system, I might not have figured it out for quite a long time<G>.
